In the dclermiiialion of these species, of which X"^ D'j and 4, 

 are new, we have l)een kijully assisted by Prof. Dr. (!. A. .). A.

In oi'der lo form aii opinion on the desti-uctiou of cellulose hy the 

 isolated species, and also to study their fructilication, pui-e cultures 

 were inoculated on pajxM' discs, which after slei'ilisalion, were drenched 

 with the aboN'C-named sohitioiu Instead of merely [dacing llie spores 

 on the paper, it was found desirable to |»ush them in il by means of 

 a platinum wii-e and then to reduce the spots thei'e to pulp. The culti- 

 vation is made at 24\ care being laken to keep the paper moist, for 

 which il was found ad\antage:)us nol lo use wahM' only bul ihesaid 

 li(pu(l, as the iulrog<Mi in particular is rapidly used up. The aboxc-named 

 moulds all grow oxer the paper discs, form llieir IVucli Ileal ion-organs
